Mapping America’s power, state-by-state

Yesterday, the Obama administration announced a plan to reduce power plant emissions (from 2005 levels) by 30% by 2030. Reuters‘ Valerie Volvoici and Jeff Mason report that 38% of US power comes from coal, and that “states which rely heavily on coal-fired power plants are thought to have the toughest tasks ahead” in complying with the rule.

Can you explain why your chart says that 40% of energy generation in Oregon is from renewables while the EIA report says 70%. Also according to your chart 50% of electrical generation in Wyoming is from coal, yet the EIA report clearly puts that number at 89%

Can you explain why there is such a massive discrepancy between your graphic and the report you claim to be referencing?
